Zoisite and Kornerupine Chemical Formula
While comparing Zoisite and Kornerupine physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Zoisite and Kornerupine chemical formula.
- Chemical formula of Zoisite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Kornerupine- Mg 3Al 6(Si,Al,B) 5O 21(OH)Walter Schumann , Gemstones of the world (2001) More from other references
Zoisite and Kornerupine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Zoisite and Kornerupine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Zoisite and Kornerupine Optical Properties during the identification of gemstone. Specific gravity of Zoisite is 3.25-3.45 whereas that of Kornerupine is 3.25-3.45.
